Acrobat activex - problems with old Acrobat versions

[Marco Turco]

Hi to all,
I have a problem using the activex class to open a pdf file because if the Acrobat Reader installed is an old version my app crash.

Is there any way to check the Acrobat Reader version before to call the activex or another way to check if we can use the Acrobat activex in that environment ?

Thanks in advance.

Sample code (from FWH):

function Main()

local oWnd, oActiveX

DEFINE WINDOW oWnd TITLE "FiveWin ActiveX Support"

oActiveX = TActiveX():New( oWnd, "AcroPDF.PDF.1" )
oWnd:oClient = oActiveX // To fill the entire window surface
oActiveX:Do( "LoadFile", "fwintro.pdf" )
oActiveX:Do( "SetCurrentPage", 1 )

ACTIVATE WINDOW oWnd

return nil

if ! PDFActivex(@arq)
return(.f.)
endif

DEFINE WINDOW oWndpdf MDICHILD OF oWnd vscroll icon oico TITLE ALLTRIM(cFile)
pdfoActiveX = TActiveX():New( oWndpdf, arq )
oWndpdf:oClient = pdfoActiveX
pdfoActiveX:Do( "LoadFile", cFile )
pdfoActiveX:Do( "SetCurrentPage", 1 )
ACTIVATE WINDOW oWndpdf MAXIMIZED valid(oWndpdf:=NIL,pdfoActiveX:end(),.t.)
